With the increasing complexity of road conditions and the increase in vehicle speeds, the impact and collision risks to which the vehicle chassis, as a key supporting structure of the vehicle, are subject have significantly increased.

[0003] When a car collides from the front, due to the lack of an effective buffer structure, the huge impact force generated by the collision will be directly transmitted to the chassis body, which may affect the overall structural stability of the vehicle and even cause damage to key parts such as the engine compartment and cockpit. Utility Model Content

[0006] Compared with the prior art, the beneficial effects of the present invention are:

[0007] The automobile chassis anti-collision auxiliary component effectively disperses and absorbs the huge impact force generated during a front-side collision by arranging an anti-collision plate on the front side of the automobile chassis body and equipping it with a combined buffer structure of a damping rod and a buffer spring. The elastic deformation of the buffer spring and the damping effect of the damping rod work together to significantly slow down the direct transmission of the impact force to the chassis body, thereby protecting the stability of the overall structure of the vehicle. A multi-stage buffer system consisting of a first protective plate, a second protective plate, a movable column, a cylinder and a damping ring is designed. During a collision, the movable column slides in a movable groove 1 of the cylinder and is simultaneously damped by the damping ring, thereby achieving a first-stage buffer. Subsequently, the relative movement between the first protective plate and the second protective plate further disperses the impact force, thereby forming a multi-stage buffer system. The impact mechanism significantly improves the protection effect. The movable column and the cylinder are connected by the sliding connection of the support rod 1 and the inner slide plate to achieve stable support, ensuring smoothness and stability in the buffering process. At the same time, the sliding connection between the front seat and the rear seat is achieved through the sliding connection of the slider in the slide groove, and the guiding effect of the connecting rod, which realizes stable sliding in the front and rear directions and avoids excessive deviation or damage caused by collision. A damping pad 1 is arranged in the movable groove 2, and a damping pad 2 is arranged on the rear side of the front seat. The damping effect of the buffer system is further enhanced through the superposition of these two layers of damping materials. During a collision, the damping pad can effectively absorb and attenuate vibration energy, reduce the transmission of vibration to other parts of the vehicle, and improve ride comfort and structural durability.

[0021] Working principle: the anti-collision plate 2 is firmly installed on the front side of the automobile chassis body 1, playing a preliminary protective role. The protective plate 1 6 and the protective plate 2 7 are respectively connected to the automobile chassis body 1 and the anti-collision plate 2 through fixed connections to form a double-layer protection structure. The movable column 10 passes through the movable groove 1 9 of the cylinder 8, but is restricted by the damping ring 14 and is in a relatively static state. The front seat 17 is fixed by the movable groove 2 16 of the rear seat 15, and is supported and damped by the damping pad 1 21 and the damping pad 2 22. The buffer system composed of the connecting sleeve 3, the damping rod 4 and the buffer spring 5 is in a natural extension state, providing a buffer space for collision. The anti-collision plate 2 first contacts the collision object and bears the initial impact force. The buffer spring 5 begins to be compressed and absorbs part of the collision energy through its elastic deformation, slowing down the transmission of the impact force to the automobile chassis body 1. At the same time, the damping rod 4 uses its damping characteristics to further consume the collision energy and reduce the vibration transmission of the shock wave. As the collision force is transmitted, the anti-collision plate 2 The guard plate 2 7 moves relative to the protective plate 1 6 through the cylinder 8, the movable column 10 slides along the support rod 12 in the movable groove 1 9, and the inner slide plate 13 slides in the support groove 1 1, ensuring the smoothness and directionality of the movement. The damping ring 14 provides additional damping to further slow down the sliding speed of the movable column 10 and absorb more collision energy. The front seat 17 moves backward under the action of the collision force, passes through the movable groove 2 16 of the rear seat 15, and the slider 19 slides along the connecting rod 20 in the slide groove 18, ensuring the smooth movement of the front seat 17. The damping pad 1 21 and the damping pad 2 22 work together to further absorb and disperse the impact force and vibration energy generated when the front seat 17 moves. The support rod 2 24 slides in the support groove 2 23 on the rear side of the front seat 17, providing stable support force to prevent the front seat 17 from excessive displacement or damage during the collision. The entire anti-collision auxiliary component ensures overall stability and reliability during the collision through precise design and manufacturing technology.

[0022] In summary: the automobile chassis anti-collision auxiliary component, by arranging an anti-collision plate 2 on the front side of the automobile chassis body 1 and equipping it with a combined buffer structure of a damping rod 4 and a buffer spring 5, effectively disperses and absorbs the huge impact force generated during a front-side collision. The elastic deformation of the buffer spring 5 and the damping effect of the damping rod 4 work together to significantly slow down the direct transmission of the impact force to the automobile chassis body 1, thereby protecting the stability of the overall structure of the vehicle. A multi-stage buffer system consisting of a protective plate 1 6, a protective plate 2 7, a movable column 10, a cylinder 8 and a damping ring 14 is designed. During a collision, the movable column 10 slides in a movable groove 1 9 of the cylinder 8 and is simultaneously damped by the damping ring 14, thereby achieving a first-stage buffer. Subsequently, the relative movement between the protective plate 1 6 and the protective plate 2 7 further disperses the impact force, thereby forming a multi-stage buffer system. The multi-level buffering mechanism significantly improves the protection effect. The movable column 10 and the cylinder 8 are connected stably by the sliding connection of the support rod 12 and the inner slide 13, which ensures smoothness and stability during the buffering process. At the same time, the sliding connection between the front seat 17 and the rear seat 15 is achieved through the sliding connection of the slider 19 in the slide groove 18, and the guiding effect of the connecting rod 20, which achieves stable sliding in the front and rear directions and avoids excessive deviation or damage caused by collision. A damping pad 121 is arranged in the movable groove 21, and a damping pad 22 is arranged on the rear side of the front seat 17. The superposition of these two layers of damping materials further enhances the damping effect of the buffer system. During a collision, the damping pad can effectively absorb and attenuate vibration energy, reduce the transmission of vibration to other parts of the vehicle, and improve ride comfort and structural durability.
